Key Points for Practice
• Infants weighing less than 2,000 g born to mothers negative for hepatitis B surface antigen should receive an initial hepatitis B vaccination at hospital discharge or one month of age, whichever comes first.
• Live influenza vaccines should be avoided in people who have received oseltamivir or zanamivir within the previous 48 hours, peramivir within the previous five days, or baloxavir within the previous 17 days.
• Approved mRNA vaccines for SARS-CoV-2 require a second dose of the same vaccine at 21 days for the Pfizer-BioNTech (mRNA-BNT162) vaccine and 28 days for the Moderna (mRNA-1273) vaccine. The CDC is adding additional safety and monitoring systems to current federal vaccine safety programs for these vaccines.
From the AFP Editors
The 2021 adult and child/adolescent immunization schedules have been approved by the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) and are accessible at https://www.aafp.org/patient-care/immunizations/schedules.html. Recognizing the difficulty of finding information in footnotes, ACIP introduced simpler and more prominent notes to clarify recommendations. Schedules for adults and children have similar designs, each with clear instructions on the cover page.
Changes to Child/Adolescent and Adult Immunization Schedules
Notable changes to both the child/adolescent and adult schedules include the addition of a new quadrivalent meningococcal vaccine option against meningococcal serotypes A, C, W, and Y for children two years and older and adults, guidance around live influenza immunization after antiviral medication use, an accelerated hepatitis A/B vaccine (Twinrix) dosing schedule for travelers 18 years and older, and further clarification on tetanus-toxoid containing vaccines in wound management.
ACIP continues to recommend routine human papillomavirus (HPV) vaccination for all patients from nine to 26 years of age and with shared clinical decision-making for those 27 to 45 years of age. People with HIV
